1This text, from one of Tolkien's early drafts, lists the birth date as 3430. However, the final Tale of Years lists the date of Elendil's march to Imladris, and presumably therefore Valandil's birth, as 3431. There is nothing to indicate that Isildur or his wife went to Imladris before Elendil, so Valandil's birth date was adjusted to match the later, canonical source.
